Enzim szállításban refers to the process of transporting enzymes within a biological system. Enzymes are proteins that catalyze biochemical reactions, and their precise location and delivery are crucial for cellular function. This transport can occur over various distances, from within a cell to between different tissues or organs.

Intracellular transport involves moving enzymes to specific organelles or compartments where they are needed. This can be achieved through vesicular transport, where enzymes are packaged into membrane-bound sacs that move along the cytoskeleton. For example, digestive enzymes are synthesized in the endoplasmic reticulum, processed in the Golgi apparatus, and then transported in vesicles to lysosomes.

Extracellular transport is also essential, particularly for enzymes secreted by cells to act in the extracellular space or in other parts of the body. Hormones often trigger the release of such enzymes. For instance, pancreatic enzymes are secreted into the digestive tract to break down food.

The regulation of enzyme transport is tightly controlled. Signals within the cell or from the external environment can initiate or halt the movement of enzymes. This ensures that enzymes are available when and where they are required, and that their activity is appropriately managed. Disruptions in enzyme transport can lead to various diseases and cellular dysfunctions.
